Community Notes on X started with a wild idea: Instead of tech companies deciding what’s true, what if you let people fact-check each other? Jay Baxter and Keith Coleman, who helped build the crowdsourced system adding context to misleading posts, discuss how the program reduces viral misinformation — and why people across the political spectrum trust it. In conversation with TED guest curator Audrey Tang, they discuss how their “surprising agreement” algorithm could reveal the common ground that quietly exists across a polarized internet. (Followed by a note from TED guest curators Divya Siddarth and Audrey Tang) (Recorded at TED2026 on April 14, 2026)

    This is the first time I’ve liked a TED talk in 5 years. These guys and Elon Musk single handedly restored free speech online.

      We are very lucky. Sadly (and obviously) there is a huge effort to supress this

      ​​@Magerquark agreed. The folks who don’t like free speech have ALWAYS been the bad guys. No exceptions.

    Thank you! I really enjoyed this and it was my first time understanding the mechanisms behind community notes on twitter (X). While I have wrestled with my internal conflicting thoughts on the CEO (Elon Musk), I have to say this really gives me hope at a bright future that includes the world of social media and AI we created. Hope for our representative democracies and mental health for future generations. Thank you again for curating this and bringing it to us, with visuals! 🙂

    First time I’ve seen a false dichotomy argument promoted on TED. Sad day indeed.

      How is it false, you mean? Please elaborate.

    The community notes on X are incredible. You know it’s great when even the owner gets community noted, so there is no bias

    Yet I see toxic people use it to spread more misinformation.

    “Show me the incentives, and I’ll show you the outcome”

    Cut the incentives to people pushing misinformation and disinformation, reduce engagement with clickbait and rage bait, and delete the algorithms designed for engagement (or enragement) instead of truth and accuracy.

    Keep your notes, but that’s not a solution to the use of social media as a tool to peddle lies.

      X has been a disaster of misinformation since Musk bought the platform to amplify his propaganda

    • @lisahansson2605

      June 19, 2026 at 3:25 am

      @vegeboy652 or… Maybe you just get to see a different world view that clashes with your narrative? How are you so sure that what YOU believe in is all truth and nothing but the truth? I, for one, am grateful that at least one platform is trying to do something about this, that does not mean one side gets to decide what is the truth.

    • @vegeboy652

      June 19, 2026 at 3:46 am

      @lisahansson2605 as an example, Musk made a recent claim was that there is ethnic cleansing of germans in germany. germany has one of the lowest murder rates in the world. a vast majority of the country is german. not really up for debate?

    This should be more aggressive like cookies. put large ugly label over it “This content is disputed and maybe incorrect”
    and if user tries to access it – ask “Are you stupidly sure?”

    • @TheRixxx

      June 18, 2026 at 5:01 pm

      except the yes button just says “are YOU stupidly sure?!?!” because they’re too stubborn to admit they’re stupidly sure and more likely would respond with a “what about YOU” instead of admitting fallibility.

    is there a community notes analogy for all aspects of life that will help serve as natural regulation across many platforms and markets? because I’m specifically thinking about the medical market that incorrectly “solves” for many afflictions through the industry standard and the same standard keeps getting peddled over and over despite it’s failures.

    Specifically, physical therapy always focuses only on the specific pain location and never sees the body as a system and even if they do see cross system weakness and try to strengthen, they never notice that the weakness is actually caused by an asymmetry. So, they end up applying bilateral exercise that only reinforces an imbalanced system which, actually needs asymmetrical exercise in an area that might be completely different than the spot causing the actual pain. The industry standard fails patients or instead only helps them to compensate until the inevitable surgical intervention rather than balancing the body as a system. The industry standard and practitioners practicing it fail people again and again and yet everyone thinks because it is normal that this is acceptable

    Hey look! We’ve got this incredibly toxic, myth-filled, right-wing hate machine, but occasionally we let people add some truth.

    How long until Elon hacks this because it’s too woke?

    Watching this talk brought me genuine relief and optimism. In a deeply divided world, learning that people with opposing views can actually collaborate to fight misinformation feels incredibly powerful. It truly restores my faith that our shared humanity can overcome digital toxicity.

    The internet, before the millennium was just computer stuff. When I say computer stuff, I mean a gigantic software depository. There was a lot of transcript educational material from history to mathematics, but nothing else. Then came Java proxy programing and the sharing networks for audio visual. The only misinformation I see is partisan politics from news sites, and AI slop on scroll feeds. It’s a response to todays passive aggressive outlook on the convenience of modern media. People want a little make-believe in their otherwise sanitized lives

    Social media is the main vehicle of misinformation poisoning western democracies. Community notes are a marketing gimmick that simply cannot keep up with the unthinkable scale and speed of nonsense and lies that are spread every second online.

  16. @fbal-meida

    Community notes as a solution for the misinformation produced by social media is liking tossing pebbles at the stream coming out of a firehose.

    But don’t let that reality burst all this chum-chum cheerio happiness and self-congratulatory nonsense.

    說的太好了,無需懼怕人工智慧,讓仁工智慧成為我們生命成長最豐沃的滋養園地。

This speaker took on gerrymandering in her state — and won! #TEDTalks

You don’t need political power to make real change, says activist Katie Fahey. She tells the story of how she led a successful movement in Michigan to end gerrymandering — the practice of drawing district lines to favor one political party — and how it all started with a simple social media post.

The Problem with Streaming — and the Case for Physical Media | Tom Rizzuto | TED
